I have a Windows 10, Dell Optiplex 9020. While cutting I keep getting the Controller Disconnected Error. SW: 2020.03.14. HW: 2020.03.12.

Device listed in windows is: CNC USB Controller Mk3 v2. Which is what I have. Driver date is 9-22-2016 ver. 1.0.0.1

I have replaced the USB cable with no change. I have tried every USB port on the front an back of the PC, there are 10. I have routed the usb cable away from all other wiring. No change. Yesterday I cut all day and it happened 3 times. Today it has happened so often I've given up cutting.

I could use some guidance. Thanks
